Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a land leveling device for leveling the top soil surface of a paddy field, which is attached to a rice transplanter or a rice field agricultural machine such as a water-seeding layer. Technique) Conventionally, a ground leveling float used as a ground leveling device has a structure in which the lower surface is concavely curved in the front-rear direction, and the vertical concave curved groove is connected to the vertical concave groove from the left and right sides by a horizontal groove.

(Problems to be solved by the invention) With the conventional land leveling device, when the field is soft when sliding,
The muddy soil is pushed to both the left and right sides, creating a large sliding resistance, causing ripples and making it difficult to level the ground accurately.Also, when turning a paddy field agricultural machine, the turning resistance is large, making it difficult to turn smoothly. There was a problem.

(Technical Means for Solving the Problems) The present invention takes the following technical means to solve the problems of the prior art.

That is, the present invention provides a structure in which a soil leveling float (16) is attached to the lower side of a rice field agricultural machine such as a rice transplanter or a flooded seeding machine and slides on the topsoil surface of a paddy field. A vertical groove αη is cut a predetermined distance toward
The structure of the land leveling device for a paddy field working machine is such that the back surface of the 0 is concavely curved upward to form a horizontal communication path.

(Operations and effects of the invention) When the agricultural machine is moving straight, there are vertical grooves in the left and right center of the soil leveling float, so the muddy water flows in here and does not push the muddy water outward, but the muddy water that fits into the vertical grooves. The upper part is ejected from the horizontal passageway, increasing the buoyancy of the leveling float and allowing it to glide smoothly. In addition, when turning, the back surface of the ground leveling float is concavely curved upward, allowing for smooth turning without pushing against muddy water in the turning direction.

According to the present invention, there is less resistance both when traveling straight and when turning, and there is an effect that mud pushing is reduced.

(Example) A soil leveling device for a rice transplanter, which is an example of the present invention, will be described in detail.

A soil leveling device for a rice transplanter, which is an example of the present invention, will be described in detail.

(1) is the vehicle body, the engine stand (3) i is installed on the front side of the running Mitsushicon case (2), the transmission case (4) is installed at the rear with all valves planted, and the transmission case (5) ft is installed, and this planted mission is installed. At the rear of the case (5) there is a control knob (
6) extends rearward and upward.

(7) is an engine. (8) is a hydraulic device unit in which a hydraulic pump, pulp, hydraulic cylinder, etc. are assembled, and n (8a) attached to the upper part of the traveling mission case (2) is a hydraulic cylinder device.

(9) is the fuel tank. αO is a companion chain case that is rotatably pivoted at the base side on both left and right sides of the traveling transmission case (2), and a wheel (11) is supported on the tip side.

■ is a seedling mounting table, which is supported on the upper part of the control handle (6) so as to be able to move left and right, and is supported by the planting mission case (5).
) is interlocked with the left and right reciprocating mechanism in ) by a moving rod (to) and a connecting fitting (α), so that it can be reciprocated from side to side.

The head is a seedling planting tool, which is attached to the left and right sides of the planting mission case (5) with a crank and a swing arm, and is designed to divide and plant seedlings from the seedling tank. The float is made of synthetic resin or the like and has a hollow interior, and its shape is such that vertical grooves αη are cut toward the rear with a predetermined width on the tip sides of the left and right center portions, and the vertical grooves α Near the rear end of the float, the back surface of the soil leveling float is concavely bent upward to provide a horizontal communication path (toward) through which muddy water can pass between the outer side and the longitudinal groove.

This ground leveling float αG is arranged at the bottom of the vehicle body between the left and right wheels αD and α.The rear part is pivotally connected to the vehicle body (1) with a metal fitting α9, and the front part is connected to the vehicle body (1) with a link ω so that it can move freely up and down.
1) is installed.

The piston of the hydraulic cylinder device (8a) and the left and right chain cases αO and αO are connected to a balance rod QD whose left and right centers are pivoted to the tip of the piston. The rods attached to the left and right ends of D are connected by an arm (C) integrally provided on the chain case αO, and the left and right wheels αυ and αB are moved up and down by a hydraulic device. The pulp of the hydraulic system is the above-mentioned earth leveling float αG and rod (foundation)
It is configured so that it can be switched in conjunction with .

In the upper configuration, place the seedlings on the seedling mounting stand (2),
When the engine (7) transmits and rotates each part, the front side of the soil leveling float (16) moves up and down depending on the depth of the tiller in the paddy field, so the pulp is switched by the rod (c) and the wheel α
The blade is controlled up and down by a hydraulic cylinder device (8a), and the ground leveling float αG is adjusted to a range of ground pressure suitable for planting seedlings.

In this manner, the wheels αD are moved up and down and rotated in accordance with changes in the depth of the tiller, thereby propelling the vehicle body (1).

Meanwhile, the seedling planting fixture α9 moves up and down, taking out seedlings one by one from the lower end of the seedling platform (2) that reciprocates from side to side, and placing the seedlings on the surface of the paddy field topsoil leveled by the leveling float αG. I'm going to plant it.

During this work, the leveling flow 10G slides in contact with the topsoil surface of the paddy field, but at this time, since the vertical groove (17) is provided in the center of the front part, a large amount of muddy water is discharged outward. The ground is leveled from the rear end side of the longitudinal groove αη, and is propelled with little ripples.) While imparting buoyancy to Qf3, it passes through the horizontal communication path (181 and is gradually discharged outward, resulting in less resistance) Also, when turning, the leveling float αG is swung around, but at this time, the muddy water passes through the entire lateral communication passage, so a large amount of the muddy water is not pushed outward. This reduces turning resistance and makes turning easier.

[Brief explanation of the drawing]

The figures show one embodiment of the present invention, with Fig. 1 being a side view and Fig. 2 being a plan view. In the figures, αG is a leveling float, αη is a vertical groove, and (to) is a horizontal communication path. be.
